They didn't pick her because her style wasn't what they were looking for, but they said she had a beautiful voice. They didn't "make" her show her face. They asked if she could take off her hat, and then she explained how some people on the internet said cruel things about her after seeing her face (she is a singer for martial arts games, etc). Then they encouraged her (the man in the hat called himself unattractive) and she gained enough confidence to show her face.
